Ichthyophthirius, I read in 2014 Peter was using a Imaging Source DMK 72BUC02 (1/2.5 inch Micron CMOS sensor (MT9P031), 2,592×1,944 (5 MP), up to 6 fps ... do you happen to know what monochrome camera Peter is using now? Just thought you might know.

Nope, the shaft wasn't marred whatsoever. Polyvars are build like a tank. From what I've read they were very high quality scopes. I'm quite lucky that all the prisms are in excellent condition, all the objectives, filters, cubes, Nomarski etc. Looks like the mirror survived falling off too and didn'...

presuming that there is something not working with the diverging mirror. Why pull the Knob off when it looks as if you could access the mirror by undoing the lighting tube access panel at the rear.

Removing a knob

I thought I'd ask before breaking something. I need to remove a knob from my Polyvar MET. It's about 4.1275 cm in diameter and it has a slight edge on the backside to grip. I removed the set screw so that's not an issue. Do they make a wheel puller for something like this? It rotates a diverging mir...

Had another bloom this morning. IF you're capable of doing the stereo cross-eye technique, this turned out really well. I also generated a parallel view. Links to a larger image are both shown below. I also tried a Black and White Infrared image using an old Nikon D70S that was converted to Infrared...
